  "abstract": "In this study, assuming the type-I 2HDM at SM-like scenario, observability of heavy neutral CP-even and CP-odd Higgs bosons $H$ and $A$ at a linear collider operating at $\\sqrt{s}=1$ TeV is investigated through the signal process chain $e^- e^+ \\rightarrow A H \\rightarrow ZHH$ where the $Z$ boson experiences a leptonic ($e^-e^+$ or $\\mu^-\\mu^+$) decay and the $H$ Higgs boson is assumed to decay into a di-photon. This signal process is motivated especially by the clean signature which leptonic and photonic events can provide at colliders, and also by the enhancement due to the charged Higgs-mediated contribution to $H$ di-photon decay at large $\\tan\\beta$ values. Simulation is based on four benchmark points according to which the Higgs mass $m_H$ ($m_A$) varies within the range $150$-$300$ ($200$-$400$) GeV. Energy smearing of jets and photons are performed, and momentum smearing is also applied to leptons. Results indicate that, for all of the assumed benchmark points, the Higgs bosons $H$ and $A$ are observable with measurable masses, and with signals exceeding $5\\sigma$ at integrated luminosities $111$ and $201\\,fb^{-1}$ respectively. Such luminosities are easily accessible to future linear colliders.",
